It switches AC loads like motors, heaters, and lighting without requiring an external RC snubber for many inductive loads, thanks to the Snubberless™ alternistor structure that provides high commutation capability. ## Snubberless™ alternistor — why it saves BOM cost The Snubberless™ alternistor structure is designed for high dV/dt capability, which means it can commutate inductive loads (motors, solenoids, transformers) without the RC snubber that a standard triac would need to prevent false turn-on. That saves one resistor and one capacitor per triac on the BOM, plus the PCB area and assembly cost. For a panel with multiple triac channels, the savings add up. The trade-off is a slightly higher on-state voltage drop compared to a standard triac, but for most 16 A loads the difference is negligible in thermal dissipation. ## Mounting and replacement in the field In a field-service scenario, you can swap it with basic tools — a soldering iron and a screwdriver — no hot-air station needed. The tab is the MT2 terminal, so if you are using a shared heatsink, ensure electrical isolation (mica washer or sil-pad) unless the circuit topology allows a common heatsink.","metaTitle":"ST BTB16-600BWRG Snubberless Triac, 16 A, 600 V, TO-220","metaDescription":"STMicroelectronics BTB16-600BWRG Snubberless™ alternistor triac, 16 A RMS, 600 V off-state, TO-220-3.

Standard triacs may require an RC snubber to prevent false triggering when switching motors or transformers. The Snubberless™ alternistor eliminates that snubber for many applications."},{"question":"How to test BTB16-600BWRG?","answer":"Use a multimeter in diode-test mode between MT1 and MT2 — you should see an open circuit in both directions (no conduction until gated). To test triggering, apply a positive gate current (50 mA min) between gate and MT1 while the triac is forward-biased; it should latch on and stay on until the load current drops below the 50 mA hold current. A standard triac tester or a simple circuit with a 12 VDC supply, a 100 Ω resistor, and a pushbutton will verify gate triggering and latching."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/BTB16-600BWRG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/BTB16-600BWRG when reusing this data.
